the part behind the vulva is as 6 to 5. A strongly granulated 
giand is situated in front of and a similar one behind the vulva. 
The spicules are long and siender and rather strongly curved 
(fig. 10). The length of the spicule from its proximal end to the 
distal tip, measured in a straight line, makes 112 p. As far as I 
have been able to ascertain there are two accessory pieces, one 
of which is embracing the distal part of the spicule and forming 
a slide for it. The length of this piece is 27 p. The other piece 
is small and situated immediately caudad to the ano-genital aperture.

Spilophora amokuræ n sp. 
PI. I, fig. 6, PI. Il, ligs. 4, 5. 
Locality : Auckland Islands. North-arm of Carnley harbour. Clay. 
Length: Female 2 mm. Male 1 .5 mm. 
Female: u — 48,3. ft = 7,i. y — 7,o. 
Male: « = 37. ft — 7,4. y — 11. 
Some specimens — males as well as females — are present. 
As far as I can see, they cannot be referred to any known species 
of the genus Spilophora. The shape of the body is — especially 
in the female — rather thick in the middle and tapers towards 
both ends. Cephalad to the vulva it tapers rather quickly until 
some distance behind the base of the oesophagus; from here it 
only tapers inconspicuously till the front end. 
The cuticle is thick and coarsely striated; it is set with points 
or oval figures, arranged transversely in striæ. The thick cuticle 
behaves rather particularly in the front end, where it ends abruptly 
at the middle of the head; the striæ and the points cease at the 
level of the base of the buccal cavity (PI. II, fig. 4). More caudad 
the cuticular points become more lengthened and at the same time 
more densely situated than in the front end; in the middle of the 
body they seem to suggest longitudinal striæ, interrupted by the 
transverse striæ. The entrance to the buccal cavity is surrounded 
by a ring of minute papillæ, and a ring of fine setæ are situated 
about in the middle of the head, just where the thick cuticle is 
ending. The buccal cavity is rather long and narrow, and the dorsal
